Sized at 5\/16-18 UNC thread with a 6-inch length under the head, this fastener is partially threaded and accepts a 1\/4-inch hex drive. Constructed from alloy steel with a black oxide coating, it delivers solid tensile strength and moderate corrosion resistance in indoor and light-duty outdoor environments. This screw is sold in a package quantity of 10. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a recognized choice for applications where fastener grade and dimensional conformance matter.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for mechanical assemblies, equipment fabrication, and maintenance applications where a recessed hex drive is preferred for flush or countersunk installation. The 5\/16-18 UNC coarse thread is widely used in general industrial and trade settings. Typical installers include millwrights, pipefitters, equipment technicians, and general contractors working on structural and mechanical connections that require reliable clamping force without a protruding fastener head.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e6-inch length under head suits deep or through-bolt applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a bearing surface in unthreaded material\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex socket drive allows use of Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 5\/16-18 UNC threaded fastener with a 6-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 1\/4-inch hex key or hex bit driver. Always verify the receiving thread is clean and properly tapped to 5\/16-18 UNC before driving the fastener.
